Sunburst Platter Update
Here's the sunburst platter released from the glass plate hump mold and flipped over. For a minute the clay had a suction to the glass and I almost thought I couldn't get it loose, but finally it came loose. I've carved in a pattern and it's now propped up and drying. The plate has sixteen rays and is about fifteen inches in diameter. The cleanup and carving took about two hours. This is definitely a labor of love.
Here's what the plate looked like fresh off the hump mold. The shiny sections are the WD 40 which wasn't dry. I used a paper towel to blot the excess oil. I'm using soft foam as a support during drying. I don't hold too much hope for this platter making it without warping. The wall sculptures I made with this same clay warped quite a bit in the once firing; lots of pieces to smash. Oh well I guess I'll have to make another one.
Look at the drying pattern on this plate, strange. Maybe I can fashion some type of prop to hold up the outer edges of the plate during firing. I could use a kiln post, but that adds more heat. As the plate shrinks during firing the post might make the plate crack. I couldn't think of a way to attach an additional footring since the sides slope gradually up. I wish I had made a removable foot ring. Wads might blow up during firing. Any other ideas to prop under the sides during firing?
Up next the warped red clay pieces and results from the second once fire. Thanks for reading and for all your comments.
